Question

The element with the maximum ionization energy in the second group is _______.

Answer 1

• Ionization energy is the energy required to remove an electron from the element.
• This energy increases across a period and decreases down the group.
• In the group $2$ , Beryllium(Be) is at the top.
• Hence, Beryllium(Be) is the element that has maximum ionization energy in the group $2$.
